She has a dirty sense of humor. ‘Hawk Tuah’ is a euphemism for the sound of spitting out sperm after a bojo. That is why Babylon Bee used it as a hilarious name for a digital currency.
I thought it was a sound made for lubrication prior to the finale. But what do I know about it, I’ve been married for 28 years. The only hawk tuah sounds I hear are after the dogs eat grass.
